VANCOUVER, Oct. 15 /PRNewswire-FirstCall/ - Northgate Minerals Corporation (TSX: NGX, NYSE Amex: NXG) ("Northgate") is pleased to announce that it has completed the sale of an additional US$20 million of 3.50% convertible senior notes due 2016 ("Convertible Notes") pursuant to the previously announced exercise of an over-allotment option (the "Over-Allotment Option") by a syndicate of underwriters (the "Underwriters") led by UBS Securities LLC.

This press release shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of the Convertible Notes in any jurisdiction in which such offer, solicitation, or sale would be unlawful prior to registration or qualification under the securities laws of that jurisdiction.
